Incidence of serious Dose-limiting Toxicity evaluated using the NCI CTCAE V5.0.
Incidence of serious adverse events (SAEs) evaluated using the NCI CTCAE V5.0 and the relationship of DLTs and SAEs with the investigational product. The assessment window is from the first dose of HMPL-506 to 30 days after last dose, or initiation of a new anti-tumor therapy, whichever comes first.
Performing anti-tumor efficacy evaluation of HMPL-506 based on Complete response (CR), Complete response with partial recovery of hematology (CRh), Complete response with incomplete hematological recovery (CRi) assessed by the Investigator. Response evaluation in AML will be conducted based on the European LeukmiaNet (ELN) 2022 criteria; response evaluation in ALL will be conducted based on the National Comprehensive Cancer Network (NCCN) Guidelines for the Diagnosis and Treatment of ALL (2023 Version 3).

HMPL-506 is an investigational small molecule being studied for the treatment of hematological malignancies, which are cancers of the blood and blood-forming tissues. It is in Phase 1 clinical development and is not yet approved for any use. The ongoing study enrolls adults aged 18 years and older in China.
HMPL-506 targets menin, a protein that plays a role in regulating gene expression. By binding to menin, the drug is designed to interfere with a protein interaction relevant to certain hematological malignancies. The Phase 1 study is biomarker selected, meaning participants are chosen based on specific molecular characteristics.
HMPL-506 is being developed by HUTCHMED (China) Limited, which trades under the ticker HCM. The company is running the clinical program for the drug in hematological malignancies.
HMPL-506 is in Phase 1 clinical development. It is an investigational drug and has not been approved by the FDA or any other regulatory authority. The single ongoing trial is currently recruiting participants, and no trials have been completed.
HMPL-506 is being evaluated in one clinical trial, NCT06387082, titled A Clinical Study of HMPL-506 in Patients With Hematological Malignancies. The Phase 1 trial is recruiting with a planned enrollment of 132 participants, is controlled, is not randomized or double blinded, and is being conducted in China.
